Hello, I made 3 videos showing how I export the character to Blender and Maya and back to unreal, now, it will not export the morph targets as unreal does not support it. U could get the character geo with Mlindbord if you got the template. The other tip I give is if u are planning to change a lot of stuff on the character, is better if u recreate all the morph targets on Blender with the same naming and same morph function as the original, as it is much easier to change the base character.
I also think these ideas would apply to any other 3d Software!

I hope it can help someone!
